Hi,
first, english is not my native language. So please forgive my spelling mistakes!
I use OMV 3 with the docker plugin. It is very cool and I would like to do more.
I have some generell difficulties understanding with docker.
Can someone explain thefollowing setting within the container?
Volumes and Bind mount:
Does this mean, that the path in the container will linked to a path ( outside this container ) on my host system?
How is the syntax for the container path? "/folder" or "folder/" ?
Volumes from:
I have no idea what this means!
If the container is already created and running. How can I edit the setting without lose the complete settings.
For example:
I installed nextcloud. Thean I changed the port of the container. I had to select the database again and assign a new admin.
How can I prevent this?
Now that I have played a lot with it, there are a lot of entries in the folder overlay2.
How can I filter and delete the unused entries?
I found a guid for delting unused container and images. But not for the entries in the overlay2 folder.
Next problem wioth overlay2:
docker/overlay2/xxxxxxxxxxxxxxxxxxxxxxx/
There are the folders: /diff , /merged , /work
If I want to edit some files in for example nexcloud.
Where do I do it?
In /diff, /merged, or /work?
Or can I link the relevant folders to my host ( see Volumes and Binds ) so I do not have to poke around in docker?
Thanks for your help.
